Low-tech Magazine has built a bicycle generator for a public exhibition on energy at the Pavillon d'Arsenal in Paris, France. Their two other bike generators can be seen and experimented with in Rotterdam, Netherlands and Barcelona, Spain.
In October, we built a third energy bicycle during a workshop at the House of the Future in Rotterdam. This bicycle generator is now used as an energy source in the community center. The House of the Future is open to the public, for details see their website and instagram.
In a future article, we will cover the construction process and technical details of these two new muscular power plants. These machines are based on spinning bikes and are more powerful than the first bike generator we built.
With electricity prices continually hitting new record highs, maybe the market is the EU?

Here's some recent data [www.creg.be] -- the first graph shows the cost of electricity for households in Belgium, France, Germany, the Netherlands and the United Kingdom. (The second graph shows the same info, but this time including VAT.)
Just taking the German data, 3,500 kWh -- a normal usage for a household, per year -- cost €1500 in November 2022; for the same amount of electricity usage you'd be paying around €600 in November 2023. This evolution is also to be seen in the Dutch and Belgian prices.
The UK and France show different trajectories: French prices have edged up slightly, but remain the lowest in this group of European countries, while UK prices only show a moderate decrease.
The prices given are prices on the open market (commercial prices), and do not take into account subsidies and the like (social tariffs) for households. As an example, for Belgium, social tariffs amounted to minus €392 for the last months of 2022, and minus €588 for the first months of 2023 up to March.

So, a highly trained athletic human powering 125w of bike generation 8 hours a day can supply 1kWh per day, get ten of these people riding in shifts and you might power one typical house GF erman house and reduce your power bill by €150 per year per rider
Do you think you could feed them sufficient calories for €0.41 per day?

Hmm.... the prices for sunflower oil are way, way up since the war... maybe lard could be used?
